Doctors at Nemours Children's Hospital in Delaware are treating a common spine condition with something called "magic rods." For one little girl with scoliosis, the rods are making a big difference. ... Sadie's spine is being treated with a technology called MAGnetic Expansion Control — or MAGEC rods. After the rods are surgically implanted, they can be slowly expanded with internal and external magnets, Dr. Suken Shah with Nemours Children's Hospital said. (Stahl and Nau, 6/26)

Two AS01-adjuvanted vaccines for different pathogens -- the respiratory syncytial virus (RSV) vaccine (Arexvy) and the recombinant shingles vaccine (Shingrix) -- were tied to a lower dementia risk, an analysis of over 400,000 U.S. older adults showed. Compared with the flu vaccine, the AS01-adjuvanted RSV vaccine was associated with a 29% increase in time without a dementia diagnosis, with a restricted mean time lost [RMTL] ratio of 0.71 (95% CI 0.61-0.83) over 18 months, reported Paul Harrison, BMBCh, DM, of the University of Oxford in England, and colleagues.

A new study shows good 2023-24 COVID-19 vaccine effectiveness in adults against medically attended COVID-19, especially against critical illness.

New research suggests that a class of antibiotics commonly used in poultry and other food-producing animals, but not in people, could contribute to antibiotic-resistant infections in humans. The antibiotic class in question is ionophores, which are used to treat the parasitic infection coccidiosis in poultry and to promote growth and prevent disease in pigs and cattle. ... Regulated less strictly than medically important antibiotics, ionophore use accounts for 37% of antibiotics used in food-producing animals on the United States. (Dall, 6/26)

Heart attack deaths have plummeted in recent years — but other types of cardiovascular disease still pose a major threat. A new study by the American Heart Association (AHA) found that overall heart disease-related death rates have declined by 66%, and heart attack deaths have dropped by almost 90%. While heart attacks are no longer the most fatal form of heart disease, there have been increases in other types — heart failure, arrhythmias (irregular heartbeats) and hypertensive heart disease (long-term high blood pressure).
